Gyvlon liquid screed is a quality-assured, pump-dispensed, free-flowing anhydrite (calcium sulphate). Its ease of application and thermal advantages with underfloor heating are seeing it become increasingly popular as an alternative to sand & cement and a sound choice ecologically.
Gyvlon screeds achieve higher thermal conductivity by reducing cover of underfloor heating pipes and greatly improving the heat performance and reaction times of the screed. This allows for a more reactive system that requires a smaller amount of energy input compared with sand & cement.
System temperature is easier to regulate due to its responsive nature and allows the building to achieve a constant temperature without the variability and thermal overshoot associated with thicker section sand cements and concretes.
Gyvlon also greatly reduces the amount of manual labour required, allowing up to 1500m2 to be installed in one day. Following installation, Gyvlon cures quickly giving sufficient strength to allow foot traffic after 36-48 hours. The binder is made from 98% recycled content – for every 1000m2 installed 34 tonnes is saved from landfill.
